f0 all whom it may concern:

Be it known that 1, Louis S. FLA'EAU, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Railway-Ties, of which the following is aspecification.

My invention relates to an improvement in rail fastenings for metallicties, and the object is to provide means whereby a rail can be fastenedto a tie and prevent the rail from creeping.

A further object is in the provision whereby the fastening means can bereversed for fastening a rail to the tie when the fish plates connectingtwo rails are received on the tie.

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claims.

In the accompanying drawingsFigure l is a view in perspective showingthe rails secured to the tie; Fig. 2 is a longitudinal sectional viewthrough a portion of the tie; Fig. 3 is a view in side elevation of oneof the fasteners, and Fig. 1 is a view of a por tion of the tie showingthe fastening means mounted on the tie in reverse position and engagingthe fish plates which connect the ends of two rails; and Fig. 5 is aplan view of the tie.

A represents the tie, and 1, 1 are elongated slots formed longitudinallyof the tie. Located centrally of the slots formed longitudinally of thetie and on each side thereof are raised portions 2, 2 forming bases forthe rails. The bases, 2, are cutaway at each end, as at 3, 3', enlargingthe slots, 1. The central portions, l, of the bases 2, are in alineinentwith the walls of the slots 1.

Received in the slots, 1, are dogs, 5, which are provided with base, 6.The body of the dogs is made hollow, and the bore is screw-threaded, inwhich is received a looking bolt, 7, which is screw-threaded to conformto the screw-threads of the body. @ne end of the bolt is squared, as at8, to permit a wrench to grasp the bolt for turning the same. The otherend of the bolt is tapered, as at 9, the tapering portion extendingtoward the extreme end of the bolt. A ing, 10, projects downwardly fromthe 3, and in the sides of the lug grooves 11 are formed in which thewalls or sides of the tie forinii'ig the slots, 1, are receivedpermitting the dogs to slide rearwardly until the projection, 12.engages the rear end of the slot. The base, 6, of the dog resting uponthe tie forms a solid bearing for the dog. When the bolts, 7, arescrewed causing the tapering portion, 9, to engage the flange of therail, the tapering portion will einbed itself into the flange so that itforms a has tening which will retain the rail in position and preventthe rail from creeping. in driving the bolt to its place over the flangeit knurls into the flange of the rail some whatand so embeds itself thatit aifords a very efficient anti-creeper, and the point of the boltthereby given a spring to some extent that takes up and is co al to theexpansion and contraction of the metal, so much so that no shock or jarwill loosen the threads in the dog or fastening.

Grooves, 13 and 1d, are formed on the base, one groove at each end, inwhich a key, 16, is received, forming a locking means to prevent thebolt from turning after it has been screwed into position for loci-ringthe rail.

In Fig. i 1 have shown the dog in a reverse position, the lug, 10,forming a stop which abuts against one end of the slot, 1, and the basewill rest upon the tie. The belt, '2, is reversed, that is, it isscrewed into he body of the dog from the opposite end from which itenters when a rail is being secured. in placin the dogs in the slots, 1,in this manner they are separated a. greater distance from each otherdue to the fact hat tie projection, 12, is only formed at one end of thelug 10. When the dog is used in this manner the groove l t, is used forreceiving the key, 15, for locking or engaging the nared end, 8, of thebolt for locking the bolt against turning. .Vhen the dogs are insertedin t 1e slots in their reversed position sufficientspace is formedbetween the two dogs to receive the ends of two rails upon the bases, 2,with the fish plates which connect the two rails togeth r. The bolts areturned after the fish plates and rails have been placed in positionsutliciently to cause the tapered ends of the bolts to obtain a properclamp upon the fish plates for locking the rails in position andagainstcree ing.

From the foregoing it will be seen that l have provided a fasteningmeans for taste ing rails to ties, which will retain the rails inposition and prevent them from creeping, and also that the fasteningmeans can be reversed whereby the rails can be fastened to the tie whenthe ends of two rails are connected by fish plates and received on atie.

It is evident that more or less slight changes might be made in the formand arrangement of the several parts described without departing fromthe spirit and scope of my invention, and hence I do not wish to belimited to the exact construction herein set forth, but:

Having fully described my invention,what I claim as new and desire tosecure by Letters Patent is 1. The combination with a railway tie havingslots therein, of dogs comprising bases adapted to be received on thetie, lugs formed on the bases and received in the slots in the tie, saidlugs having grooves therein in which the walls of the slots arereceived, bolts having screw-threaded engagement with the bases providedwith tapering ends, which are adapted to engage a flange of the rail forlocking the rail in position and means received between the bases andbolts for locking the bolts against movement.

2. The combination with a tie having slots therein, of reversible dogscomprising bases slidably mounted on the tie and lugs on the bases forlimiting the movement of the bases.

3. The combination of a tie having slots therein, of reversible dogscomprising bases, means on the bases for locking the rails and lugs onthe bases received in the slots and provided with grooves, which areadapted to receive the walls of the slots, said lugs adapted to engagethe tie for limiting the movement of the dogs.

4. The combination with a tie having slots therein, of dogs slidablymounted on the tie and received in the slots for locking the rail inposition, said dogs capable of being reversed whereby the dogs areseparated to receive therebetween and lock to the tie the rail providedwith fish plates.

The combination with a tie, of dogs slidably mounted on the tie, meanson the dogs for locking the rail in position, said dogs capable of beingreversed, thereby separating the dogs'farther apart whereby a railprovided with fish plates may be re ceived between the dogs and lockedto the tie.

In testimony whereof I afix my signature, in the presence of twowitnesses.
